b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * "x86 system devices" refers to the suite of hardware components which are
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * common to the x86 platform and play important roles in the system
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * architecture but can't be enumerated/discovered through industry-standard
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * bus specifications. Examples of these x86 system devices include:
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * * Memory device
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * * Non-PCI discoverable IOMMU or DMA Remapping Engine
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * * Non-PCI discoverable IOxAPIC
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * * Non-PCI discoverable HPET (High Precision Event Timer)
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * * ACPI defined devices, including power button, sleep button, battery etc.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * X86 system devices may be discovered through BIOS/Firmware interfaces, such
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * as SMBIOS tables, MPS tables and ACPI tables since their discovery isn't
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * covered by any industry-standard bus specifications.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * In order to aid Solaris in flexibly managing x86 system devices,
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * x86 system devices are placed into a specific firmware device
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * subtree whose device path is '/devices/fw'.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * This driver populates the firmware device subtree with ACPI-discoverable
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * system devices if possible. To achieve that, the ACPI object
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * namespace is abstracted as ACPI virtual buses which host system devices.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * Another nexus driver for the ACPI virtual bus will manage all devices
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * connected to it.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * For more detailed information, please refer to PSARC/2009/104.
